I would like to print/view one list that is just today's tasks but divided into list view - i.e. under heading for each list (but with none of tomorrows or later's tasks)

I have lists like "phone calls" and "emails" etc. It would be great to be able to sort my tasks by date due first and then category 2nd. That way, I would get a list of tasks due for Today separated by categories. So, when I'm at my phone, I would have my list of calls all organized together, when I'm at my computer I'd have my emails for the day listed all together. Right now my list of to do items for today are all in one big messy clump based on the order I thought of them and input them, not based on the lists that I created to be organized.

I usually try to schedule my week on sundays, and this suggestion would be great.

It is not really a suggestion, it is a missing feature making any.do useless.
It is the reason I am still looking for a Todo list manager...

Add a view mode with days of the week. Monday —> Sunday
This would allow to efficiently break up tasks that occur on day-by-day timescale.

I have many tasks, nearly 600. I want to be able to sort by task creation date to see my oldest tasks first

It will be so helpful if Any.do add a filter, to show tasks that assigned to certain user (either free or premium one)

I'd love to be able to create custom filters to add more power to how I can sort, search, organize my to dos. For example, if I could create a custom filter called "Top 3 Priorities" that I could click on to display any tasks that I've tagged with that filter, I could with one click see my top 3 tasks for any particular day. I could do this by creating a list called Top 3 Tasks, but then I couldn't see that task in multiple lists.
